Investors are closely monitoring social unrest in Europe, led mainly by France. According to experts at international asset managers, October could be a complicated month for global markets considering the US midterm elections, rising bond yields, and geopolitical and domestic political risks, which do not appear to be losing momentum.
“October is a month that strikes fear into the heart of many investors due to the dramatic, high-profile sell-offs experienced that month in 1929, 1987, and 2008. The negative perception of October is more psychological than real, as historically it has not been the worst month for stock market investing. However, psychology is important when it comes to the markets, and with bond yields hitting multi-year highs, several major elections around the corner, and the US midterm elections just a month away, it seems October is taking us straight into the danger zone,” acknowledges Kristina Hooper, Chief Market Strategist at Man Group.
From Aberdeen Investments, they note that short-term selling pressure may not be over. “Rising oil and gas prices have highlighted pre-existing weaknesses in the fiscal credibility of the US, the UK, and France, as well as persistent inflation, while forced liquidations by leveraged investors have amplified these moves. The only factor that could clearly halt this trend is an improvement in the geopolitical situation in the Middle East,” they indicate.
The Case of France
For now, the big focus is France, as spreads on its sovereign debt have reached new highs while fiscal consolidation seems increasingly distant. It is worth noting that the wave of riots and violence that has broken out responds to social discontent resulting from government cuts and rising inflation. “With the French 10-year bond close to 5%, the 140-billion-euro net savings program proposed by Le Pen arouses skepticism by requiring a gross adjustment of 185 billion euros and relying on unrealistic GDP growth of 1.8%, compared to real estimates of between 0.5% and 0.8% for 2026. The lack of a solution to the French deficit revives the ghost of the 2012 sovereign debt crisis, placing the European Central Bank before the dilemma of letting debt fall and harming confidence in the euro, or intervening and rewarding fiscal indiscipline, creating moral hazard in the rest of the region,” points out Javier Cabrera, analyst at XTB.
For Erick Muller, Director of Product and Market Strategy and Co-Head of the Asset Allocation Group at Muzinich & Co, political gridlock and the proximity of the 2027 elections make it difficult to adopt corrective measures and could prolong uncertainty in the markets. “France is a good example of the difficulties developed economies face in controlling public spending. In 2026, its deficit stands at around 5.6% of GDP, and the interest cost on debt is increasing considerably. This year, interest expenditure has gone from a forecast of 70 billion euros to approximately 80 billion. In 2027 it could reach 92 billion, and in 2028 be close to 100 billion. To put these figures in perspective, the government is trying to find savings of 53 billion euros, something I don’t think it will achieve. We are talking about an increase of around 30 billion in interest payments in just three years. It is a very difficult situation to solve,” he explains.
In his opinion, France’s problem is that the economy is slowing down and the political landscape makes any fiscal response extremely difficult. “Expected growth for 2026 has been reduced to practically half of what was initially expected, which also affects public accounts. Markets are asking what the answer is to this deterioration, and for now, they are not finding any satisfactory one,” he adds.
Return of the Bond Vigilantes?
In this context, investors are paying close attention to the spike in debt yields and the course of the Federal Reserve—have the “bond vigilantes” returned? For Giordano Lombardo, founder, CEO, and CIO of Plenisfer Investments (Generali Investments), yes; furthermore, he warns that the boom in AI investment, increasingly financed by debt, and rising public deficits are increasing pressure on fixed-income markets and elevating stagflation risks.
According to his analysis, the increase in bond yields extended to public securities of other countries. “All major fixed-income markets registered negative returns, except China. In recent weeks, concerns surrounding government bonds of certain Eurozone countries have resurfaced strongly, and France seems to be the epicenter of the crisis this time due to the sharp increase in its public deficit and the prospect of elections that could further worsen the sustainability of public finances,” he states. Moreover, he considers that waves of pessimism in the fixed-income market also affected the technology sector.
His main conclusion is that we have entered a phase of structural bear market conditions for bonds. “However, in recent months, the role of the Federal Reserve has once again become the dominant factor driving short-term movements in the bond market. In addition, the fiscal policies of major economies have all been expansionary, at least over the last fifteen years and especially following the post-pandemic measures introduced in 2020. In the US and Europe, there do not appear to be political forces interested in returning to the fiscal discipline of previous decades,” he qualifies.
